Machined Plastic Parts

Engineering plastics replace metal where the job wants light weight, corrosion resistance, quiet running or self-lubrication. A nylon gear runs quieter than a steel one; a UHMWPE liner outlasts a steel chute against abrasion; an acetal bush holds size where nylon would swell.

Acetal is the stable, precise one — it machines beautifully and holds dimensions, so it suits gears, bushes and anything with a tolerance on it. Nylon is tougher and quieter but absorbs moisture, which means it moves dimensionally in wet service. UHMWPE has the lowest friction and the best abrasion resistance of the three, which is why chute and hopper liners are made from it, but it is not for precision parts. PTFE handles temperature and chemical attack that would finish the others. PEEK is where the duty justifies the cost.

Describe the load, the speed, the temperature and the surface the part runs against, and we will tell you which we would use. That is a more useful conversation than a datasheet comparison.

A dimensioned drawing or a DXF is ideal. Mark which dimensions are critical and whether the tolerance has to hold across a batch — those two notes change how a part is machined and are worth more to us than tightening every dimension on the page.

Send a drawing, a DXF, a sketch or the part itself. We quote the finished job — material, machining, finishing and freight — rather than a rate you have to assemble yourself, and we confirm the critical dimensions and tolerances against your drawing before anything is cut.

Everything happens in our Gold Coast workshop: cutting, machining, forming and welding on one floor, so a job does not move between suppliers to get finished. Completed work ships Australia-wide from the capital-city depot nearest you.
